Information About 1794-TBNF
The 1794-TBNF is part of the Allen-Bradley Flex I/O platform and is engineered to serve as a robust field-wiring interface for distributed I/O installations. It features a NEMA-style terminal base design with clearly separated terminal strips for I/O, common, and supply connections. The unit integrates fuse protection directly at the terminal level, enhancing system safety and simplifying maintenance. It is commonly used in industrial automation systems where Flex I/O output modules require individual circuit protection and reliable screw-clamp termination.
Key Features:
- Flex I/O system compatibility: Designed for use with Allen-Bradley Flex I/O modules.
- Integrated fuse protection: Includes eight 5 × 20 mm fuse holders for I/O circuits.
- Screw-clamp terminals: Provides secure and vibration-resistant wiring connections.
- NEMA-style terminal base: Suitable for industrial control panel environments.
- Pre-installed fuses: Supplied with fuses for 1794-OA8 module applications.
- Multi-module support: Compatible with OA8, OA8I, OW8, and OW8XT modules.
- Clear terminal layout: Separates I/O, common, and supply terminals for clarity.
- Protective wiring cover: Helps safeguard field wiring and improve organization.
- High voltage rating: Supports AC and DC applications up to 250 V.
The 1794-TBNF delivers the reliability and precision required for protected field wiring and output module integration in Flex I/O industrial automation systems.
